Orientation performance of high resolution SAR imagery

Using high resolution Synthetic Aperture Radar (SAR) Orientation is vital for improve the accuracy of mapping. Two experiments were designed to examine the spatial distribution and quality of the ground control points (GCPs) on the influence of geographical deviation. Take different selection method for the spatial distribution of the GCPs in the first set of experiments and get GCPs with different distributed manner for the impact of geographical deviation; Take different selection method for the quality of the GCPs in the second set of experiments and get GCPs with different quality selection manner for the impact of geographical deviation. From the two groups of experimental results revealed that the errors of road intersections or corner points is evidently smaller than that of mountains and rivers boundary and the consistency error of uniform spatial distribution is more obvious than nonuniform spatial distribution.
